Researchers have discovered a highly efficient way to produce high energy photon beams. The obtained energy is a billion times higher than the energy of photons in visible light. These high-intensity gamma rays significantly ...

Ever play with a magnifying lens as a kid? Imagine a lens as big as the Earth. Now focus sunlight down to a pencil tip. That still wouldn't be good enough for what some Texas scientists have in mind. They want to make light ...

(Phys.org)—A trio of researchers with The University of Texas has found a possible way to create gamma ray beams by firing a laser beam at a piece of plastic. In their paper published in Physical Review Letters, David Stark, ...

Using ever more energetic lasers, Lawrence Livermore researchers have produced a record high number of electron-positron pairs, opening exciting opportunities to study extreme astrophysical processes, such as black holes ...

Twenty years ago, Philip Platzman and Allen Mills, Jr. at Bell Laboratories proposed that a gamma-ray laser could be made from a Bose-Einstein condensate (BEC) of positronium, the simplest atom made of both matter and antimatter ...

The brightest gamma ray beam ever created- more than a thousand billion times more brilliant than the sun- has been produced in research led at the University of Strathclyde- and could open up new possibilities for medicine.

(PhysOrg.com) -- Building a nuclear gamma-ray laser has been a challenge for scientists for a long time, but a new proposal for such a device has overcome some of the most difficult problems. In the new study, Eugene Tkalya ...
